This has often been the case in Taiwan. Usually it is due to either copy cat syndrome or due to either China trying to sabotage Taiwan, or Taiwans government previous sellouts to china coming back to bite us in the ass.
Basically, to answer your questions. yes, lack of export creates a rock bottom price. No, farmers are not getting a fair price. They never were before either, it is just worse now. Middlemen and retail outlets get all the real profits with almost no risk.
This is why sometimes you see certain juices hit the shelves at 711 cheap. right now it is lemon, guava and somewhat passion fruit. you can see the cartons for cheap (remembering after % and shelving fees/promotions etc rt marts, 7s etc probably take 50~60% off the retail price. then the logistics and costs of the producer (hence low % real juices with added sugar usually).
I know a lot of guava farmers that have just stopped going to the farms now. in the last 2 years we have seen farm wholesale prices hit 5nt/kg (not tai jin) if papaya, banana, guava and lemon. Pineapple would of too if japan and other countries didnât help the government find a sollution for that round of Chinese economic warfare.
Sometimes farmers actually lose money.
You still see lots because some farms are contract farms. which means 2 important things: They have a contractual agreement to supply a certain quantity in certain times; and, they usually have a minimum price guarantee. which is often very shitty, but better than losing money.
Big scale farms like Taiphone and such are a different ballgame with different rules.
Edit for markups.
imagine this scenario as a rough guide.
Farmer sells for 10nt/kg. You fit 5~20kg per box (varies greatly by crop). box costs 10nt. trucking from south to north warehouses/wholesalers are usually in the 20~30nt/box range. Letâs low ball it and call shipping 30nt for 10kg. thatâs 3nt/kg just to ship.
Labour low ball is 1200/8hour day. legally 1300 is minimum. you need to pay people to harvest, grade, clean and pack each box. Or just sell it cheaper to a local distributor with a setup in place with refrigeration etc. common nation wide.
This completely ignores the cost of trees/seeds, land prep, pipes (double now from last year), fertilizers, death sprays etc and all that labor too.
And people still throw away food. this is why over various threads I repeat: Food is too cheap!
